Have a look in the LPR thread. It's more about zoom, focus and, especially, shutter speed at night. Current preferred, if memory serves me right, is a Dahua B5231-Z12. That's only 2MP but with the right zoom and angle of attack it works very well according to the experts in LPR.

The go to camera is the Z12 @sebastiantombs suggests.

Don't chase MP, especially for plates. Most are 2MP and many commercial businesses still use analog.

Also read up on LPR subforum for tips on how to set up LPR. In short, you want the image to be just about only the car in the frame. Anything bigger and you lose the plate.

At night the image will be B/W and an all black image and all you will see is head/tail lights and plate and nothing else. This is accomplished with a 1/2,000 shutter speed - you need a fast shutter to capture plates and unless you have a TON of light at night, the image will be black.

Further, you cannot use this camera as an overview cam - that is people's biggest mistake is to try to do too much with one cam. If you want to also be able to see color and make of car, etc., then you need an overview camera in addition to a camera just for plates, at least for night time.

Welcome to the forum.

It will all depend on your specific criteria. Distance, lighting, angle of attack, vehicle speed, etc.

But asking for a 10MP cam for LPR is like asking for a Bugatti for delivering pizza. It will take quite a lot of cash to get a 10MP cam that gives you what you want.

Now if you are asking for 90% plate caps after dark with some lighting and about 60-75 feet out head on, the Dahua B5442E-Z4E is a 4MP cam that does well. It has an 8-32mm varifocal lens. I am not using this cam specifically for LPR. I am using it for vehicle ID of color, make, model, and description. But it does very well at picking up plates in this install. I have not optimized it for LPR. I have other cams for LPR.

My two LPR cams are the Dahua IPC-HFW5241E-Z12E which is the newer version of the cams mentioned above. This is a 2MP cam with a 5-60mm varifocal lens. I am in the process of installing these. Other folks here have had good success using these cams for LPR.

Welcome @anakimatu

Sorry to hear that.

Plan to have a lot more than just one camera to do what you are attempting...

Please see the various threads on this topic and see what other members have been doing.

Hi, sorry, does any one know what wavelength the camera uses IR 850? 920 ?nm

if I were to supplement with an IR blaster or an Array would it help ?

It depends. The only real way to find out is to test. It will depend on the distance, angle and other things in the field of view that could reflect the IR back at your cam.

The Dahua that you bought is an 850nm.

For a micro SD card. You can have video or stills written there by the cam that you could access via the web browser. It is a good way to ensure that you might still have data if the NVR or BI PC were to die.

What cam did you get? Can't answer your mount question without that info.

I am assuming you got the Z12 as it is kinda pain to adjust that in my opinion - I ended up loosening the screws on the inside part of the support to move it to the approx position I thought it would need to be in when I mounted it.
